ates to improvements in dethe handling of bulk material, such as e, such veyor or the like.

vention is more particularly described The in with reference to which:

Figure 1 is a side elevation construction.

Figure 2 is a side elevation of fied arrangement.

3 is a corresponding plan view to Fig- Figure ure 2.

Figure 4 is an end to Figures 2 and 3 taken on the A scoop or the li crank lev be displa frame forms part of a t which can be embedded to be removed, whilst t er 2, the

the accompanying drawings in of one form of part of a modisectional view corresponding line A.A.

ke tool I is mounted on a bell pivot 3 of which is adapted to frame 5, which rough, the front end of as a rigid part,

into the pile of material he remaining part of the belt conveyor 1 one, or both, of

which is driven from any suitwer connected to the driving this pulley III by like gearing to a pair of sprocket connected to a parallel pair of sprocket wheels I2 by means of a chain which is connect crank the stop I1.

It will conse wheels I I on either I2 side pivoted a connecting I3 to one of the rod I4, the ed either directly lever 2 or to an The second arm I6 of apted to co-operate with quently be seen that as the sprocket are rotated the connecting rods I4 of the frame 5 will be reciprocated to cause reciprocation of the lever 2 and the scoop I, from the po 1 to the p in which catch I8a up spindle 3 that this terial adj osition shown in dotted position a locking releasing the scoop I pawl on it is freed from a recess 3a in the sition shown in full lines in Figure lines in Figure 1, I8 having a and lever 2, so

may fall by gravity into a load of maacent to the end 6 of t he trough 5. As

the connecting rod I4 then moves backwards a charge of material will be drawn by the scoop I up the trough 5 until it is taken up by means of the belt conveyor 1.

As the connecting rod its travel as shown in full arm I6 on the scoop lever the stop I1, and raise this tion shown in full lines, in be locked by means of the catch upon it, engaging as a recess in the pivot spindle of this.

The scoop arm 2 may, if desired, be provided as shown with an extension arm I9, although this is not essential, whichmay have one or more picks or auxiliary scoops arrangedto draw the material forward into range of the main scoop I.

The conveyor 1 may be of any known form. It may be of any desired length, and may work in 20 tandem with other similar conveyors. In the particular arrangement shown, one of its pulleys 9 is supported on an extension 2| of the wheel frame 22, carrying the whole device, so that this end of the belt conveyor 1 is adjustable in angle relatively to the main trough part 5 about the pivot 23, which angularity is adjustable by means of a turn buckle 24.

In the alternative arrangement shown, particularly with reference to Figures 2, 3 and 4, the connecting rod I4 instead of being connected 3 of the pick or scoop arm 2 is connected to a pivot on the end of an arm 25, rigid with pivot 3 and lever 2, the arm being either counter-weighted as shown in dotted lines, or otherwise mounted to ensure that the scoop I on the end of the arm 2 falls into the position shown in dotted lines when the connecting rod I4 reaches the forward end of its travel.

As shown more particularly with reference to Figures 3 and 4, instead of a single scoop I, this may be made of a number of scoops 26, 27, all mounted about the same pivoted spindle 3.

I4 reaches the end of lines in Figure 1, the 2 will strike against lever into the posi- Which position it will pawl I8, which has a 10 above indicated with 3 preventing rotation These scoops may be independent of one another I declare that what I claim is:

A device for handling bulk material comprising a trough, a pivoted scoop; a bell crank lever carrying the pivot of said scoop, means to displace the pivot of said bell crank lever in a rigid guide path parallel to the floor of said trough, and means to periodically trip the other arm of said bell crank lever to raise the scoop clear of the 039 material at the end of its travel and 'meansto lock the bell crank lever with the scoop in its raised position and means to release said lock at the other end of the travel of the scoopparallel to the trough.
